Application filed May 14 1913. Serial No. 767,723.

To all whom it may concern: V

Be it known that we, WILLIAM THORNEY and Earn. THORNEY, citizens of the United States, residing at Denver, in the county of Denver, State of Colorado, have invented a i new and useful Combustion-Engine, of which the following is a specification.

My invention relates to new and useful improvements in combustion engines and more particularly to those in which anonvolatile fuel may be used.

The object of the invention. is the provision of means whereby the non-volatile product is properly vaporized to successfully operate the engine. Y

' A further object is the provision of means for initially operating the'engine with a volatile fuel until the non-volatile can be prop-- erly vaporized.

With the foregoing and other objects in view which will appear as .the description proceeds, the inventlon resides inthe combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within'the scope. of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the engine- Fig. 2 is a detailed section of the connection for the non-volatile fuel.

In the drawings the letter A'indieates a combustion engine of the well known construction having the carburetor 1, the inlet manifold 2 and-the exhaust manifold 3 of ordinary construction. A supply pipe 4 leading from a supply of volatile fuel connects to the carburetor 1. A pipe 5 is connected to the inlet manifold and enters the I exhaust manifold and passes through the exhaust as shown in dotted lines in Fig. 1. This pipe passes out'of the exhaust as shown at 6 and to this pipe 6 is connected the supply of non-volatile fuel. An extension 7 is secured to the pipe '6 and passes up into and through the exhaust as shown in dotted lines; Fig. I, and then passes out'of the exhaust as shown at 8. The end 8 is open so as to allow air to pass freely into the pipe.

The non-volatile fuel is supplied by means of a pipe 9 which is connected to the cup 10 having the float regulating device 11 connected to the valve 12. A passage 13 leads from the cup ,10 into the pipe 6. A screw bureter connection.

valve-l li's provided for cutting off the supply of nonvolatile fuel to the pipe 6.

Surrounding the-exhaust is a jacket 15 to which is securedaapipe 16 leading to the pipe connecting the carbureter 1 andinlet manifold 2. A lever 17 is provided for'closing the end of the Having fully described my invention in detail I. will now fully describe the operation. In starting the engine itis necessary to use the volatile fuel until the exhaust has become properly heated, to vaporize the non-volatile fuel. -The supply .of volatile fuel is then'cut off and the valve l lopened to allow the non-volatile fuel to pass from the cup 10 into the pipe-6.- Air will enter the end 8 of thepipe 7 and will become heat ed before passing the fuel inlet. This air passing through the pipev 6- will suck the fuel from the cup spraying thesame and properly vaporizing 1t. As the fuel passes through the pipe in the exhaust it will become properly vaporized to successfully operate the engine. By providing the jacket 15 and pi e 16 I can admit heated air into the manifold during the initial operation of the engine when the volatile fuel isbeing used. Having fullydescribed the invention what I claim as new and desire to secure by Letters Patent is y 1. In combination with a' combustionengine having a carbureter, an intakemanifold and an exhaust manifold, a pipe connected to the intake-manifold and passing through the exhaust, saidpipe being open at the endoutside of the exhaust, an extension on said pipeintermediate the ends extending outside, of the exhaust, a supply of nonvolatile fuel connected to said extension, and a supply of volatile fuel connected to the carburetor.
